Crown New Materials Launches Mica Sheet Adhesive Tape Series to Enhance Protective Solutions for New Energy Vehicles

With the rapid development of the new energy vehicle industry, power battery systems demand even stricter safety and reliability standards for high-temperature insulating materials. Thanks to its excellent heat resistance, electrical insulation, and flame-retardant properties, mica sheets have become a critical material in thermal runaway protection solutions for new energy applications, widely used in battery pack cover plates, cell thermal insulation, and high-voltage component isolation.

Data shows that in 2024, the global market demand for mica sheet bonding tapes in power batteries reached 14.23 million square meters, with China accounting for 10.61 million square meters. By 2030, the global and Chinese markets are expected to grow to 32.72 million and 27.48 million square meters, respectively.

Although mica materials have broad application prospects, their inherent difficulty in adhesion poses significant challenges to bonding processes. Therefore, bonding tape products for mica sheets must be systematically optimized across multiple dimensions, including substrate selection, adhesive system, release liner structure, die-cut compatibility, and environmental durability. In response to these challenges, Crown New Materials proudly launches the “Mica Sheet Bonding Tape Series,” delivering reliable, efficient, and eco-friendly bonding solutions tailored for new energy power systems.

Triple Breakthroughs: Fully Empowering Mica Sheet Bonding

1. Poor wetting and adhesion? Crown New Materials solves it with “conformability.”
Mica sheets have weak cohesion, and conventional pressure-sensitive adhesives struggle to wet and adhere quickly, often causing unstable bonding, delamination, or peeling issues, which severely impact automated assembly efficiency and product reliability.

Crown New Materials’ Mica Sheet Bonding Tape Series uses PET or kraft paper substrates combined with specially formulated acrylic adhesives, offering excellent wetting and strong adhesion on mica surfaces. Its easy-release liner design allows residue-free removal, improving assembly efficiency and stability.

2. Fragile and thin? Crown New Materials ensures precision die-cutting.
Mica sheets are brittle and thin, demanding high precision in die-cutting and adhesive structure stability. Traditional tapes often experience liner tearing, adhesive stringing, rough edges, lifting, or residual adhesive during punching, compromising product quality and electrical safety.

The Mica Sheet Bonding Tape Series from Crown New Materials delivers clean-cut edges, no residue, no tearing, and high-speed die-cutting compatibility. It fully supports die-cutting and assembly processes, effectively improving production efficiency and product consistency.

3. Moisture, wrinkling, deformation? Crown New Materials enhances storage and transport adaptability.
Mica sheets are often bonded over large areas, requiring consistent adhesive application. Any liner deformation caused by moisture can compromise adhesion, weakening overall electrical insulation and flame-retardant performance.

Crown New Materials’ upgraded liner materials improve dimensional stability and assembly consistency during storage, handling, and bonding, ensuring reliable performance under high temperature and humidity conditions while protecting system-level insulation and product reliability.

More than just tape—it’s a part of the new energy safety system.
Amidst new energy technology advancements and stricter battery safety standards, mica sheet bonding tape has become a critical component of thermal insulation and electrical safety in power systems. Leveraging its adhesive material expertise, Crown New Materials accurately addresses the characteristics and application needs of mica sheets, providing more reliable, efficient, and eco-friendly bonding solutions to help new energy clients build safe and stable power systems.
